8 Ways to Optimize AWS Glue Jobs in a Nutshell

-
Image
  Improving the performance of AWS Glue jobs involves several strategies that target different aspects of the ETL (Extract, Transform, Load) process. Here are some key practices. 1. Optimize Job Scripts Partitioning : Ensure your data is properly partitioned. Partitioning divides your data into manageable chunks, allowing parallel processing and reducing the amount of data scanned. Filtering : Apply pushdown predicates to filter data early in the ETL process, reducing the amount of data processed downstream. Compression : Use compressed file formats (e.g., Parquet, ORC) for your data sources and sinks. These formats not only reduce storage costs but also improve I/O performance. Optimize Transformations : Minimize the number of transformations and actions in your script. Combine transformations where possible and use DataFrame APIs which are optimized for performance. 2. Use Appropriate Data Formats Parquet and ORC : These columnar formats are efficient for storage and querying, signif

AWS Vs Azure Load Balancers Top Insights

-

In AWS, you have three types of load-balancers. In the case of Azure, you have only two load balancers. This post tells you the comparison between these two.


1. AWS Load Balancers:

  • Application Load balancer
  • Network Load balancer
  • Classic Load balancers.


a. Application Load Balancer


Balancing of HTTP and HTTPS traffic and provides advanced request routing targeted at the delivery of modern application architectures, including micro-services and containers. 


Operating at the individual request level (Layer 7), Application Load Balancer routes traffic to targets within Amazon Virtual Private Cloud (Amazon VPC) based on the content of the request.


b. Network Load Balancer


Network Load Balancer is best suited for load balancing of Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Transport Layer Security (TLS) traffic where extreme performance is required.


c. Classic Load Balancer


The Classic Load Balancer provides the basic load-balancing across multiple Amazon EC2 instances. 


It operates at both the request level and connection level. Classic Load Balancer the real use is for applications that build within the EC2-Classic network.


AWS vs Azure load balancers explained in this post for your quick reference.

2. Azure Load Balancers:


In the case of Azure load balancers, it has two types. And is needs many steps to make it workable:


  • Create an Azure load balancer
  • Create a load balancer health probe
  • Create load balancer traffic rules
  • Use the Custom Script Extension to create an IIS-site
  • Create virtual machines and attach them to a load balancer
  • View a load balancer in action
  • Add and remove VMs from a load-balancer


The Azure has two types of load balancers. Those are:

  • Public Load-Balancer.
  • Private( Internal) Load-balancer.


i. Public Load Balancer


A public load-balancer can provide outbound connections for virtual machines (VMs) inside your virtual network by translating their private IP-addresses to public IP-addresses. 


Public Load-Balancer's purpose is to load balance internet traffic to your VMs.


ii. Private Load Balancer


In the case of an internal (or private) load balancer, you need private IPs for the frontend only. 


The purpose of this is to load-balance the traffic inside a virtual network. It is true that accessing of frontend from an on-premises network is a hybrid scenario.


iii. Azure Load Balancer Features


  1. Load balancing of internal and external traffic.
  2. Connectivity of Azure virtual Machines.
  3. Security.

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same.

During the import of my python script, I got the import error cannot import name datetime. My Script: datetime.py My script's intention is to find whether the minute value is odd or not. Python Logic from datetime import datetime odds = [ 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 , 17 , 19 , 21 , 23 , 25 , 27 , 29 , 31 , 33 , 35 , 37 , 39 , 41 , 43 , 45 , 47 , 49 , 51 , 53 , 55 , 57 , 59 ] right_this_minute = datetime.today().minute if right_this_minute in odds: print ( "This minute seems a little odd." ) else : print ( "Not an odd minute." ) ImportError I have imported my datetime.py from Linux. It gives an error

How to Check Kafka Available Brokers

Here's the command to check the list of brokers present in a Kafka Cluster. You can say the Broker is the heart of the Kafka cluster. In simple terms, it works as a process. The main function is to receive messages from publishers and gives permission to access messages by consumers. How to Check Available Brokers in Kafka Here is the command: linux$  ./zookeeper-shell.sh zookeeper-IPaddress:2181 | "ls /brokers/ids" Just use the above command to get the number of brokers present in your host (Kafka Cluster). What is Default Broker-id in Kafka  The default broker id is -1 . When you create a new broker, it adds to -1. Then, it gives a new broker id. The broker ids will be generated from  reserved.broker.max.id + 1. Types of broker ids. Use assigned Zookeeper generated broker id. According to Wiki: Kafka runs on a cluster of one or more servers (called brokers), and the partitions of all topics are distributed across the cluster nodes.  Additionally, partitions are replicat

SQL Query: 3 Methods for Calculating Cumulative SUM

-

SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than or
